dietary supplement, 30 capsules/1 pack.
Swanson Beta-Sitosterol 320 mg 30 capsules is a dietary supplement containing natural ingredients: beta-sitosterol from pine bark, zinc, and selenium from selenium yeast, enclosed in a convenient capsule. Phytosterols are plant-derived sterols found in cell membranes. They participate in the regulation of intracellular processes and serve as a defense against herbivores. Combined with sugar, they form glycosides often used as medicines. There are over 150 known plant sterols, one of which is beta-sitosterol. Consuming 1.5–2.4 g of plant sterols daily reduces the risk of developing coronary heart disease and helps maintain normal blood cholesterol levels. Zinc is involved in the metabolism of carbohydrates, vitamin A, macronutrients, and fatty acids. This element contributes to the maintenance of healthy skin and bones. Additionally, it affects fertility and maintains normal plasma testosterone levels. Interestingly, it helps maintain healthy vision. One of zinc's most significant benefits is supporting the body's immune system. Selenium is a trace element that plays important roles in the human body. Primarily, it supports the body's immune system and ensures its proper functioning. It also affects thyroid function, as it is essential for the conversion of the thyroid hormone thyroxine (T4) to triiodothyronine (T3). Selenium also contributes to the health of hair and nails. This trace element also plays a cellular role in spermatogenesis, i.e., sperm production. This means it influences human reproduction. In the case of other cells, it protects their contents, i.e., DNA, proteins, and lipids, from oxidative damage. In summary, the Swanson Beta-Sitosterol 320 mg 30 capsules dietary supplement is a product with a pure composition containing naturally derived plant beta-phytosterols, zinc, and selenium in a convenient capsule form.
